[0026] like Figure 1 and Figure 4 As shown, the utility model provides an assembled self-locking exterior wall insulation anchor bolt. The assembled self-locking exterior wall insulation anchor bolt comprises: a steel bar locking hook 1, a locking sleeve 3, an extended self-locking sleeve 4 and a locking head 5. The steel bar locking hook 1 comprises: a hook body and a locking threaded rod, the hook body is adapted to the corresponding steel bar 2 in the steel bar frame, the hook body is buckled onto the steel bar 2, the locking threaded rod is a screw straight rod, and the locking threaded rod is fixedly connected to the hook body. The locking sleeve 3 is a pipe fitting with openings at both ends, the locking sleeve 3 is provided with an internal thread, the locking sleeve 3 is provided on the locking threaded rod, and the locking sleeve 3 is configured to squeeze the steel bar 2 into the hook body. The extended self-locking sleeve 4 comprises a straight tube with an opening at at least one end, at least one anti-stripping thread buckle is provided inside the straight tube, and the end of the straight tube away from the opening is fixedly connected to the locking threaded rod. The locking head 5 includes a self-locking column and a fixing piece. The self-locking column includes a straight rod and a locking tooth. At least one locking tooth is fixed on the straight rod. The locking tooth is adapted to the anti-stripping buckle. When the self-locking column is inserted into the straight tube, the anti-stripping buckle only allows the locking tooth to move in one direction. The fixing piece is fixed to the end of the self-locking column. The fixing piece is configured to fix the insulation board to the self-locking column.

[0027] In some examples, the rebar locking hook 1 comprises a hook body at the front and a locking threaded rod at the rear. The hook 1 is integrally cast or cut from steel. When the hook body is hooked onto a rebar 2 within a corresponding rebar frame, the locking sleeve 3 is screwed onto the locking threaded rod. The locking sleeve 3 and the hook body then press the rebar 2 together, securing the hook body to the rebar 2.

[0028] The extended self-locking sleeve 4 can be a pipe fitting with an open end. Multiple anti-stripping threads are arranged sequentially within the extended self-locking sleeve 4 along its extension direction. The extended self-locking sleeve 4 is fixedly connected to the locking threaded rod. A sealing member, such as a sealing plug, is then used to seal the open end of the extended self-locking sleeve 4. Concrete is then poured onto the steel frame to form the wall. The open end of the extended self-locking sleeve 4 should be flush with the wall surface or slightly protrude, for example, by 1-5 mm.

[0029] Remove the blocking piece at one open end of the extended self-locking sleeve 4, and insert the self-locking pin of the lock head 5 through the insulation board, that is, the self-locking pin passes through the insulation board, and the fixing piece is in contact with the surface of the insulation board. Then, insert the self-locking pin extending to the outside of the insulation board into the extended self-locking sleeve 4, and the locking teeth on the self-locking pin and the anti-stripping screw are completely engaged, so that the insulation board is tightly attached to the wall and is not easily removed.

[0030] Or the length of the open end of the extended self-locking sleeve 4 beyond the wall surface is greater than or equal to the thickness of the insulation board. When the insulation board is pressed onto the wall, the extended self-locking sleeve 4 passes through the insulation board, and then the lock head 5 is inserted into the extended self-locking sleeve 4, and the fixing part is pressed to the surface of the insulation board. Example 2

[0031] like Figure 5 As shown, based on Example 1, the hook body of this embodiment comprises a cylindrical rod with a through slot disposed therein, the through slot extending perpendicularly to the direction of extension of the cylindrical rod. The cylindrical rod is provided with external threads extending from one end of the cylindrical rod toward the through slot, and the distance from the external threads to the bottom of the through slot is less than the diameter of the steel bar 2. The cylindrical rod is coaxially fixedly connected to the locking threaded rod, and the external threads on the cylindrical rod mate with those on the locking threaded rod, allowing a smooth transition of the locking sleeve 3 from the locking threaded rod to the hook body.

[0032] The hook body can be made of a rod, with an external thread provided at one end and a through slot provided at the other end. The through slot is perpendicular to the rod. Of course, to prevent the steel bar 2 from falling out of the through slot, the interior of the through slot can be a cylindrical curved surface, and the opening of the through slot forms a hook shape with the interior of the through slot. When the steel bar 2 is placed in the through slot, the locking sleeve 3 is screwed onto the external thread of the rod until the locking sleeve 3 presses the steel bar 2 to the inner wall of the through slot. In addition, to prevent the steel bar 2 from falling out, the locking sleeve 3 can be screwed to a position that fully or partially covers the opening of the through slot, preventing the steel bar 2 from falling out of the through slot opening. That is, the diameter of the steel bar 2 is larger than the width of the opening remaining after the locking sleeve 3 covers it. Example 3

[0033] Based on Example 2, the locking threaded rod is provided with a blind hole at one end away from the cylindrical rod, wherein the blind hole is provided with an internal thread. The extended self-locking sleeve 4 further includes a self-locking rod, which is a threaded rod and is screwed into the blind hole.

[0034] The rebar locking hook 1 is made of metal, and the extended self-locking sleeve 4 is made of hard plastic. At least one anti-screw hook is arranged in sequence along the centerline of the straight tube. Each anti-screw hook is a reducer, with the larger diameter end of the anti-screw hook being closer to the open end of the straight tube than the smaller diameter end. The larger diameter end of the anti-screw hook is fixedly connected to the outer wall of the straight tube.

[0035] The locking tooth is a conical structure adapted to the anti-stripping thread buckle, and the locking tooth includes a transition surface and a locking surface. The transition surface is a reducer structure, and the small diameter end of the transition surface is smoothly transitioned to the side wall of the straight rod. The locking surface is a vertical ring, and the outer ring of the locking surface is fixedly connected to the large diameter end of the transition surface, and the inner ring of the locking surface is fixedly connected to the side wall of the straight rod.

[0036] The extended self-locking sleeve 4 has a self-locking structure. In current technology, reliable, economical, and simple self-locking structures are typically made of hard plastic materials such as PVC and PP. The extended self-locking sleeve 4 can be integrally cast. Unlike the rebar locking hook 1, the strength requirement is higher only in the tensile direction. Therefore, in this application, the rebar locking hook 1 and the extended self-locking sleeve 4 are separately provided. Example 4

[0037] Based on the above embodiment, the fixing member is a plate or at least three circumferentially arranged rods. The fixing member further includes a clasp having a conical structure. The clasp is fixed to the end of the rod away from the self-locking column. The clasp is configured to be pressed into the insulation board to secure the insulation board to the rod.

[0038] The fixing part can be a plate, such as a circular plate. A buckle is provided on one side of the plate close to the self-locking column. The buckle can be a raised cone. When the fixing part presses the insulation wall, the raised cone will be pressed into the insulation wall and the insulation wall will be fixed.

[0039] Alternatively, the fixing member may be at least three rods arranged in a circle, for example, four rods arranged in a circle, and one end of each rod is fixedly connected to the end face of the central self-locking column. Snap teeth are provided on the rods to achieve compression and fixation of the insulation wall.

[0040] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
